Analysis

(ref:TQ-diff-abi) Difference between the ensemble mean of analyses a) and c) POL-CTRL, b) and d) ABI-CTRL for the spatially averaged vertical profiles of temperature (a and b in \(K\)) and specific humidity (c and d in \(gkg^{-1}\)) calculated over the interior domain (red box in Figure @ref(fig:domain)a) for each analysis cycle.

(ref:UV-diff-abi) Difference between the ensemble mean of (a) and (c) POL-CTRL, and (b) and (d) ABI-CTRL analyses for the spatially averaged vertical profiles of the zonal wind (a and b, in \(ms^{-1}\)) and meridional wind (c and d, in \(ms^{-1}\)) computed over the interior domain (red box in Figure @ref(fig:domain)a) for each analysis cycle. The black contours correspond to the zonal and meridional wind for (a, c) POL and (b, d) ABI.
